PathBuilder S330/S310 Overview

Application Support
Key Benefits
The PathBuilder S330 WAN access switch provides cost-effective T1/nxT1 or
E1/nxE1 connections between local campus and enterprise networks via private
leased line or public carrier ATM services so you can extend high-speed Internet
access, Frame Relay, and ATM network service—as well as voice and video—out to
your branch offices. Using the built-in ATM Forum standard-based inverse
multiplexing capabilities, you can integrate voice, video, and high-speed data
services over the same WAN link.
The PathBuilder S330 and S310 switches use the same hardware, but the
PathBuilder S330 software allows more interfaces to be used. The following
subsections describe the features of each unit in greater detail.
The PathBuilder S330 base platform offers the following features:
T1/nxT1 ATM UNI or E1/nxE1 ATM UNI with up to four interfaces for
aggregated high-speed of 6Mbps WAN access. Each user-to-network interface
(UNI) can be used alone or bundled into a group using the Inverse Multiplexing
for ATM (IMA) standard, accommodating branch office growth from a single
T1/E1 (1.5/2 Mbps) bandwidth to four T1s/E1s (6/8 Mbps).
With the optional 4-port IMA expansion card installed, the PathBuilder S330
switch provides up to eight ports of T1/E1 UNI with IMA.
The PathBuilder S330 switch allows up to 70 msec of differential delay
between T1s/E1s in a single IMA bundle. The unit also supports an automatic
mechanism for removing failed lines from an IMA bundle, ensuring the
resiliency required for your mission-critical applications.
Multiple connections to Ethernet segments over ATM WAN and support of
bridging, including learning, aging, filtering, spanning tree, and classical IP over
ATM (RFC 1577 (2225)) through the standard Ethernet 10BASE-T port and the
optional Ethernet 10/100BASE-T (Ethernet PCI) module. The standard Ethernet
10BASE-T port supports half duplex only, while the optional Ethernet
10/100BASE-T port supports both half and full duplex.
